In 2010 systems using the current refrigerant used for residential A/C
will be phased out.
The current R-22 refrigerant will be replaced with new refrigerants
like R-410a
with names like Puron
and Prozone.
Did
you know that a 13 SEER A/C system is 30% more efficient than the standard
(minimum allowed) 10 SEER systems used since 1992?
